repeated checks for compiler and SDK slow down the progress.

Is your feature request related to a problem? Please describe.

I use xmake in Visual Studio and I enable the plugin.vsxmake.autoupdate. Every time I change xmake.lua to modify the structure of the project or add files for the target, it consumes much time (5~6s) during update vsxmake project -k vsxmake. I found that there are some repeated checks for the compiler and SDK. Is it possible to check only once for better startup speed?

The vs probe has a global cache and won't take much time. It is possible that the detection of qt directories is causing more time, but there is no way to optimise this at the moment. You can try to remove some unneeded configurations.

xmake project -k vsxmake -m debug -a x64

only generate for debug/x64

I have a large project using a lot of packages and project generation takes 20-25s because of it. I think it could be improved because most packages are the same between my modes, and could be fetched only once.
